Ichi chinyorwa chinoongorora mhedzisiro yewebhu tension control panguva yeTeflon yakakwirira-tembiricha tepi yekuputira paPTFE substrate flatness uye adhesive coating kufanana. Migumisiro pane substrate flatness: kushushikana kudarika elastic muganho kunokonzera kusagadziriswa kwepurasitiki kutambanudza uye mutsipa (longitudinal elongation, transverse narrowing), kuumba slackness, wrinkles uye wavy mapatani; PTFE inonyura pasi pekukakavadzana kwakasimba inova 'yakaoma' mushure mekutonhora, zvichikonzera kusaenzana kwepamusoro; kusaenzana kuchinjika tension kubva kuhurombo husina kuenzana hunogadzira micheto yakamonereka, pakati mabhururu, uye periodic tight-yakasununguka mamaki.

Ichi chinyorwa chinoongorora shanduko yemaitiro muPTFE high-temperature jira panguva yekukwegura. Zvikamu zvina: PTFE coating microstructure — molecular chain scission and oxidation (carbonyl/carboxyl group formation), crystallinity change (kusimuka kwekutanga ndokudonha), micro-crack uye pinhole formation, pamusoro peupfu; Girazi fiber substrate uye interface - saizi / coupling agent kuora kunokonzera kurasikirwa kwe bonding, interfacial debonding uye delamination (blistering, white areas), glass fiber network erosion and embrittlement, alkali metal oxide precipitation inokonzera kushungurudzika kuora; Macroscopic chimiro uye chitarisiko - shanduko yeruvara (chena → beige → brown → dema), shrinkage deformation uye kupeta, kukwenya kwepamusoro uye kurasikirwa kwekupenya, kuita upfu pakubata, kurasikirwa zvachose kwekushanduka. Essence yekuchembera: kufambira mberi kwe 'coating degradation → interface kutadza → substrate degradation.'

Ichi chinyorwa chinovhara maitiro ekudzora sintering nguva yePTFE yakakwirira-tembiricha machira. Core control method: line speed kugadzirisa. Sintering nguva = inoshanda kupisa chikamu kureba ÷ jira rekufamba kumhanya. Inoshanda sintering pachikumbaridzo i350°C (pamusoro peiyi tembiricha inoverengwa senguva yekupisa). Multi-zone tembiricha kugovera: preheating (100-250 ° C), sintering (360-395 ° C), yakakwirira-tembiricha kugadzika (380-390 ° C), kutonhora (pasi 300 ° C). Reference nguva pa 380-390 ° C: lightweight (0.08-0.13mm) 30-60 seconds; chiyero (0.18-0.25mm) 1.5-3 maminitsi; inorema (≥0.35mm) 3-5 maminitsi. Kuzivikanwa uye kugadzirisa: pasi-sintering (yakaderera simba, kuputika kwehupfu, micro-cracks) → kuderedza kukurumidza kuwedzera nguva; over-sintering (yellow, brittleness, white fumes) → wedzera kukurumidza kupfupisa pekugara. Tembiricha-nguva yakaenzana inobvumira kutonhora kwepamusoro-soro kumhanyisa (395-405 ° C, masekonzi) kana kudzika-kunonoka kutonhora (360-375 ° C, 5-8 maminetsi).

Ichi chinyorwa chinotsanangura maitiro ekuchinja musimba rakabatana rePTFE yakakwirira-temperature tepi yakanamatira layer mushure mekuchembera kwakanyanya. Maitiro matatu-matanho: Kurapa kwemashure ekukwira kwepamusoro (kutanga kwekushisa kwepamusoro-kupisa pa 200-260 ° C, mapoka akasara anogadzirisa anoramba achiyambuka, kubatana kunowedzera zvakanyanya); Yakagadzikana equilibrium nhanho (crosslinking nzira dzekupedzisa, kubatana kunoramba kwakagadzikana kwenguva refu); Kudzikira uye kuderera nhanho (yakawandisa nguva / tembiricha inokonzeresa kuderera kweketani huru, kubatana kunoderera, kunamira kunopfava uye kunova tacky). Midzi inokonzeresa kutadza kwakabatana (kubvaruka kwemukati kusiya zvisaririra) uye kusvina-kunze (kutonhora kuyerera kubva kumicheto nekuda kwekudzikira modulus) kunoongororwa.
